A dipole with charges ±q and separation 2a is located a distance x from a point charge +Q, oriented as shown in the figure.
Find an expression for the magnitude of the net force on the dipole in the limit x≫a.
What is the direction of the net force? Enter answer as number of degrees counterclockwise from the positive x-direction.
F = kq1q2/r2
The Attempt at a Solution
I honestly cannot think of a solution for this problem. Currently I am stuck on the dipole piece. How does one come up with an equation using the limit x >> a? I guess a better question would be what that means in terms of figuring out the net Force on the dipole. I am simply confused on where to start or how to begin besides using F = kq1q2/r2
